Answer:
The correct answer is letter "B": differences in perception versus reality.
Explanation:
In the discussion, it is clear to see that Sam believes it is unfair to tax "responsible" people so others can benefit from the money collected. Whereas Teresa believes that providing part of those funds to promote health care programs is fair. The different points of view reflect a difference in perception over reality mostly in Sam's cases since not only "responsible" people are taxed. Everybody with revenue is. Even people who eventually benefit from social programs pay taxes too.
